Free Energy(∆ G ) Thermodynamic constant that gives the amount of energy required for or released by a reaction - kcal/mol - Reaction that require energy ; positive - Reation that release free energy ; negative - Energy must be released overall to form a base-paired structure - The stability of the structure is determined by the amount of energy released
The Overall Free Energy of a double-stranded structure ∆ G total= ∆ G i + ∑ ∆ Gx + ∆ ∑ Gu ∆ Gi : the free energy for initiation of a double helix Positive value: + 3.4 kcal/mol It applied to intermolecular duplex formation ∑ ∆ Gx:the sum of the individual reactions involved in propagating the double helix as each base pair is added the formation of each base pair releases energy ; negative ∑∆Gu: the sum of individual instances encountered as the double helix is propagated in which the opposing bases are not complementary the energy required to hold these bases in an unpaired state ; positive
The Free Energy of formation for a potential base-paired region
